Described stator shaft orientation positioning, is provided with, in casing ends, the bonnet covering described shaft core.
Beneficial effects of the present invention
1st, using on field, the use field of cross grinding electro spindle of the present invention is face grinding machine, and electric main shaft structure is simple, tight
Gather；Main drive chain length is zero, and motor directly drives to main shaft, has that driving error is little, main shaft inertia is little and dynamic characteristic
The advantage such as good, powerful demand when big torque, High speed finish machining when can meet face grinding machine low speed rough cut.Improve simultaneously
The dynamic balancing of face grinding machine, decreases the vibration and noise that drive system is brought.
2nd, in structure, the built-in circulating water passage of cross grinding electro spindle of the present invention and grinding fluid cooling duct, follow
Ring water cooling passageway cools down to main shaft bearing support member, motor stator part, and grinding fluid cooling duct is carried out to shaft core
Cooling.Arrange temperature sensor at some passages, thermostatic control is carried out to whole main shaft.Reduce main shaft to become because temperature rise produces
Shape, improve main shaft running accuracy it is ensured that in long-play main shaft performance stability.
3rd, in structure, cross grinding electro spindle of the present invention is arranged using the angular contact bearing of typical " two after first three ",
Structure is simple, compact, and first three angular contact bearing is mainly used in bearing larger axial grinding force and radial grinding force, latter two
Angular contact bearing plays the effect of Auxiliary support.Ensure that the high rigidity of whole main shaft, high running accuracy.
Further illustrate technical scheme below in conjunction with the accompanying drawings.
